  • Patent number: 5509495
    Abstract: A drive assembly for a motor vehicle comprising a forward engine supported in two bearings on the vehicle body, a rearward drive unit supported by way of at least one elastic bearing, and a central support tube arranged in-between. This central support tube is connected on the forward end with the engine in a movable manner and on the rearward end with the drive unit in a rigid manner. A drive shaft or a central corrugated shaft which has a torque-transmitting joint in the area of the connection extends in the central support tube. The engine is connected with the drive unit by way of an uncoupling device which can be adapted as a function of main excitation directions of the engine and which comprises a connecting joint which holds the engine so that it can be angular moved in the main excitation directions. The connecting joint and/or a bearing device is used for the torque support.

  • Patent number: 4213632
    Abstract: An independently suspended wheel rear axle suspension for motor vehicles of the torsion spring type is improved by the provision of a bolster that is designed for reducing the suspension space requirements, while providing optimal noise damping and stable wheel guidance. The improved bolster includes, according to a preferred embodiment, a thrust bearing, a rigid longitudinal support that is connected to the vehicle body by the thrust bearing for providing only vibration insulation and guiding, a support bearing, and a resilient spring member connected to the vehicle body by the support bearing for receiving the preponderant torque of the torsion spring and the vehicle weight, while providing vibration insulation. The longitudinal support means is mounted so as to be elastically displaceable under the influence of forces in the vehicle longitudinal direction, while being relatively rigid under the influence of forces in the vehicle transverse direction.
